How is this not survivor bias?

Seems like they were just citing anecdata anyway, so calling out a statistical error doesn't seem worthwhile.

I believe their main point is that humans are much more tolerant of latencies than is commonly assumed. I remember reading about Carmack's early work with VR and sensor delays and screen refresh delays on the order of 100ms and as high as 400ms and it still being enjoyable[1]. At 60fps you've got about 16ms per frame to work with, and I'm sure the human mind doesn't need input -> change in image within a single frame (though I'm sure pro gamers would notice).

I even see people using and enjoying shadowpc + vr headsets, where delay between head turn and change in image can be nauseating.

Have you used it recently? People are definitely blowing the whole input lag thing out of proportion. Sure it might not hold up if you're a competitive gamer, but for the leisure gamer it's definitely not noticeable assuming you have a decent internet connection.

I have a gigabit connection with ~10ms latency and Stadia feels awful even for single-player games.

Yeah but when did you try it? They've made tons of improvements since it was first launched.

Of course it is to a degree (I don't remember anyone I personally know complaining about the latency, but there is very likely a self-selection that those that would didn't try or didn't talk about it). But I'm not sure why that matters when addressing the claim that the product is a priori useless?
